In general, this invention provides a box for carrying sand to be released from the box upon the operation of a releasing mechanism that deposits the sand in the form of an emblem on a surface against which the device is held.

Referring to the figures, in Fig. 1 a form of the carrying and depositing device of this invention is designated by the numeral 10. The device It] is shown positioned above a surface ll upon which rests an emblem l2. The device In, as shown in Fig. 2, is composed of a casing l3 which has side walls M, a top wall [-5, and an open bottomlli.

The open bottom N5 of the casing I3 receives a plate assembly I! which is retained in position at the bottom of the casing l3 by screws I18. The plate assembly I1 is made up of a grooved sole I9 on which is fastened a perforated screen plate and felt layer 2|, which is adhered-to the upper surface of the perforated screen plate 20. The felt layer 2i is perforated to corres ond with the perforations of the perforated screen plate 20. In turn, a sliding cut-off plate 22 is positioned on the felt layer 2!. The sliding outoff plate 22 is independent of the plate assembly H.

shown in Fig. 3, the sliding cut-off plate 22 is retained on the plate assembly I! by means of a post 23 and a spring 24. The post 23 is mounted on and integral with the plate assembly I1. The spring 24 has a coil portion 25 wrapped around the post 23 and a spring arm 26 extending from the post 23 and engaging with a dog 21 mounted on the cut-off plate 22, as seen in Fig. 3. The sliding cut-off plate 22 is provided with an opening 28 to fit over the post 23 and to permit the plate 22 to reciprocate with relation to the post 23 and the rest of the device l0. At one end the plate 22 is provided with an upturned flange 29. This flange 29 is engageable with a lever 30 which has a li 3| inserted in a slot 32 in the flange 29, as shown in Figs. 2, 3, and 5; The lever 30 extends through a slot 42 in the top wall 15. The spring 24 exerts a pressure on the cutofi plate 22 through the dog 21. This pressure tends to move the plate 22 to the left of the device W, as seen in Figs. 2 and 3. The cut-off plate 22 is thus held in the position shown in Fig. 2 with the lever 38 drawn against a partition 33 which extends laterally across the casing l3 and is spaced a short distance from the right end wall I4, as seen in Figs. 2 and 3. A fulcrum point 43 of the lever 3|] bears against the top wall l5 of the casing I3 at the slot 42.

The sole I9 is provided with grooves 54 which define the shape of the emblem to be formed by the device It. As shown in Fig. 4, the grooves in this embodiment outline a cruciform. The grooves 34 have walls 35 which are oblique to the perpendicular and flare outwardly from the center of the grooves 34 in a downward: direction. Perforations are provided in screen plate 25. These perforations conform to the shape defined by the grooves 34. As shown in Figs. 2 and 5, the felt layer 2| is provided with perforations 31 which correspond to and combine with the perforations 36 of the screen plate to provide passageways 38- from the interior of easing l3 to the grooves 34.

The cut-off plate 22 is provided with perforations as which correspond in configuration to the perforations 35 of the screen plate 2t and perforations 3'1 of the felt layer 2 I. In theclosed position of the device Hishown in Figs. 2 and 3, the cut-off plate 22 is positioned with its perforations 39 out of register with the passageways 38 so that the passageways are closed by the plate 2 2. In-Fig. *5, the'cut-off plate 22 is shown moved tothe open position of the device It by the actuation of the lever 35 so that the perforations 39 are in alignment with the passageways 33 and open to the grooves 34.

The device It is operated to produce the emblem l2 on the surface H by releasing sand or other suitably granulatedmaterialthrough the perforations, passageways and grooves. To operate the device of this invention the casing i3 is filled with sand through a port 453. The port 45' is closedwith a cover 4| which is sprung in place to retain the sand in the casing l3. As explained above, the cut-off plate 22 is normally held in a position in which its perforations 39 are closed by the felt layer 2| and its supporting screen plate 28. In this closed position thelever 3D is retained with its disengaged end elevated from the top wall |5- of thecasing- I5; and with its lip end drawn back against the partition 33 and retained in this position by the action of the spring 24. Upon depressing the raisedend of thelever 35 theaction of the lever about the fulcrum 43 moves the cut-off plate 22 to the right, as seen in Fig. 2. Thecut-off plate 22 is moved into alignment with the passageways 3-8 and grooves 34, and when so in alignment permits the escape of the sand from the casing l3. The escaping sandfills the grooves 34 and rests on the surface conforming to the grooves 34'.

When the sand thus fillsthe grooves 34 11; is molded into a shape defined by the grooves 34. In the embodiment shown in Figs. 1 ms, the sand is molded into a crucifix emblem by the. grooves 34. Upon release of the lever 30 the sliding cutofi' plate 22 returns to the closed position, cutting off any further flow of sand: from the casing. l3,

and the device ll] may be removed from the surface I leaving the emblem l z formed thereonin the shapedefined by. thegrooves 34. A. sufficient quantity of sand may be retained within. the casing |3-to provide.for:several repetitionsof this the perforated.

4 operation without refilling the casing. In each repetition the same steps of operation take place, forming identical crucifixes of perfect shape and form each time.

A modification of this invention is shown in a device 44, illustrated in Figs. 6 and '7. The device 44 is similar to the device If} described in connection with Figs. 1 through 5 having a casing 45 made up of four side walls 45, a top wall 4?, and an open bottom 48. The open bottom 48 is closed with an assembly 49 made up of a sole plate 50 and a felt layer 5|. A sliding cut-off plate 52 cooperates with the assembly 49. The sole. plate 50 is fastened to the casing 45 by screws. 53 and retains the plate assembly 59 in the open bottom 48 of the casing 45. The felt layer 5| is supported on the sole plate 55. The sole plate 5|] has grooves 54 which are formed to the shape of the emblem which it is intended the device 44 shall reproduce upon operation. The sole plate 50: also has perforations 55; penetrating through the sole plate 55. The perforations 55 are formed along the grooves 54. The felt layer 5| has perforations 56 corresponding in pattern to the perforations 55 so. as to form passageways 51 through the assembly 49. The sliding'cut-ofi' plate 52 has perforations 58in the same pattern as perforations 55 and 56. In the closed position of the device. 44 the perforations 58 are blocked by the felt layer 5|. and the sole plate 50.. In the open position of. the device 44, perforations 58 align with the passageways 5'5 to provide an" opening. from the interior of the casing; 45 through the grooves 54.

The sliding cut-off plate 52 is provided with means. for shifting its position horizontally across the felt layer 5| so that it can be slid from the closed position. shown in the. figures to an open position. The means for sliding the cutoff plate. 52 is comprised of an arbor 59 which is mount'ed: in. a bearingplate 50 and a counter bearing plate. 6| attached to opposite side walls 45 of. the casing 55. The arbor 59 carries a crosspin: 62. which is mounted perpendicular to the axis of the. arbor. 59. A pair of. yoke. members 63., extending vertically from the upper surface. ofv the sliding. cut-off plate 52, are provided with central. slots 64 which receive the outer ends of; the cross pin 62. so. that the yoke members 63 are engageable by the cross pin 62. The arbor. 59.; thus connected to the cut-off plate 52, canbev madev toactuate the cut-off plate 52 upon reciprocation. The. left end; of the arbor 59, as shown in Figs. 6 and'i, is:provided with a push button 65Which extends through asuitable. openingSB in thecasing 45. and: ismanipulatablefrom outsideof the casing. 45;. The arbor 59 and the push button 65 are held in the closed position shown in Figs. 6 and 7 by a spring. 6? which seats against the bearing. plate 52: and bears against the push button 55.. to urge the push button 65 and thearbor. 55-to the'left, as shown in Figs. 6 and 7.. The spring 51' isretaineddn a spring casing 68 which is integral with the bearing plate. 60.

In the position shown in.Figs..6 and'7, the sliding cut-off plate 52- is shown in a closedposition. The extended push button 65. may be moved in- Ward against the spring 61, and through the cross pin |i2the arbor 59moves the yoke members 63 to the right, as seen in Figs. 6; and. '7. The perforations 58 are thus brought into alignment with the; passageways 5.1. The casing: 45. is filled: with sand through a. port" 69' in the top Wall 41. Upon aligning the perforationsz58' with the passageway 51 the sand in the casing 45 is deposited in the'grooves 54 and shaped to the form of the desiredemblem as determined by the shape of the grooves 54.- The release of the push button 65 allows the spring 61 to return the arbor 59, cross pin 62, yoke members 63, and sliding cut-off plate 52 to the closed position, cutting off the fiow of sand out of the casing. Upon removal from the decorated surface the device 44 leaves the desired emblem formed thereon.

- Another modification of the device of this'invention is shown in the structure illustrated in Figs. 8, 9, and 10. As described in connection with the above embodiments of this invention, a-device 19 is shown having a casing 'I| made up of four side walls "I2 and a top wall 13; The casing II has an open bottom I4. The device I9 is provided with a modified means for distributing and releasing sand or other granulated material to form the desired emblem of this invention. Referring to Fig. 9, a sole plate I5 is provided with grooves I6 and perforations 'II penetrating the sole plate I5. -A cut-off plate position an end 91 projects through the'sole plate I8 slides on the upper surface of the sole plate I5 7 and is reciprocated by suitable means. Inward of the cut-off plate I8 in the casing II a screen plate I9 is mounted on posts 89 and spaced from the cut-off plate I8. The cut-off plate I8 is provided with perforations 8| in the same pattern as the perforations II of the sole plate I5.

The screen plate I9 is likewise provided with perforations 82 in a pattern conforming to the perforations I1 and BI. The perforations 82 of the screen plate 19 are fixed directly over the perforations II of the sole plate I5. In the closed position of the sliding cut-off plate IS the perforations 8| are closed by the sole plate I5. Upon operation of the reciprocating means the cut-off plate I8 is moved to the open position in alignment with the fixed perforations I1 and 82 of sole plate I5 and screen plate 19. In this position sand or other granular material retained above the screen plate I9 is. free to pour through the perforations and into the grooves "I6.

A partition 83 extends laterally across the casing II and provides a chamber 84 in which the screen plate I9 is positioned. The chamber 84 is lined with liner pieces 85 which extend along the side walls I2 of the casing "II and are mounted on the side walls I2. The screen plate I9 is arranged to abut at its periphery the surface of the liner pieces 85 and thereby provide a seal of said chamber 84 and to allow the chamber 84 to be a repository for the sand or granular material to be deposited by the device 19. The sand or granular material which is introduced into the chamber 84 through a port 86 in the top wall I3 is supported above and away from the sliding cut-off plate I8 by the screen plate I9.

A gear box 81 is also provided within the casing II by the partition 83. The gear box 81 contains the means for moving the cut-off plate I8. The cut-off plate I8 is retained in slidable engagement with the upper surface of the sole plate I5 by guides 88. As seen in Fig. 8, the bulk of the cut-off plate I8 is positioned beneath the chamber 84. A tab 89 however, extends into the gear box 81. The tab 89 has mounted on it a rack 99 which is engaged by a cylindrical gear 9|. A frame 92 standing upright in the gear box 81 supports a reciprocal plunger 93 which is mounted in a right angle flange 94 at the upper end of the frame 92. Seated between the flange 94 and a collar 95 on the plunger 93 a spring 96 forces the plunger downward so that in normal I5 and beyond the bottom of the device 19, as seen in Fig. 9. The-plunger 93 also carries a rack 98 which engages the gear 9|.

In the operation of the embodiment of the invention shown in Figs. 8, 9, and 10, the device I9 is placed on a surface and pressed downward, forcing the plunger 93 upward from its normal position and turning the gear 9| with the rack 98. The gear 9| in turn moves the rack 99 which slides the cut-off plate I8 from its normal closed position into an open position. In the open position the perforations 8| of the cut-ofi-plate I8 are in alignment with perforations I1 and 82, as explained above. In this position the. sand from the chamber 84 is deposited in the grooves I6 to provide the formation of an emblem as described in connection with the above mentioned embodiments. Upon removal of the device I9 from the decorated surface, a figure in sand remains with the predetermined outline. In this embodiment the spacing of the screen plate I9 from the sole plate I5 and cut-off plate I9 allows the cut-:off plate to seal in the remaining sand.

- It is important in this device that no sand dribble from the perforations II and grooves 16 upon removal of the device I9 from the decorated surface.

As a feature of this invention the granular material may be retained on the decorated surface by a previously applied adhesive. For example, an adhesive layer 99 may be applied to a surface I99, as shown in Fig. 11. Sand |9| deposited by the device of this invention is deposited on the adhesive layer 99 and retained on the surface I99 by the adhesive layer. The adhesive layer 99 may be applied to the surface |99 in liquid form by suitable means, such as brushing or spraying. Suitable adhesion for many purposes may also be obtained by applying the adhesive in a solid viscous state from a backing of material which carries the adhesive from which it can be applied to the decorated surface. For example, pressure sensitive cellulose tape carries an adhesive. Applying the adhesive from such pressure sensitive tape to the surface and then removing the cellulose backing will leave adhesive on the decorated surface. This adhesive is relatively inconspicuous and yet will retain a granular material upon deposition from the device of this invention.

Among other advantages, this invention provides a simple means for quickly depositing a material on a surface in a predetermined shape. As shown in Fig. 1, a crucifix of sand or dust may be formed on a surface, such as the top of a casket. The deposition of the material and the formation of the resultant emblem is a simple matter with the device of this invention and can be performed with the utmost solemnity and dignity.

It is a further advantage of this invention that the operation of the device is certain and complete in its simplicity. One motion provides the desired emblem.

It is another advantage of this invention that the grooves forming the emblem have walls which, flaring outwardly and downwardly, form the material when it is deposited in the grooves into sloped piles. The material thus deposited in sloped piles retains its form after the removal of the depositing device of this invention. Therefore, at a solemn ceremony the emblem will not change shape after the removal of the depositing device.

it is' another advantage: of this: inveniti'omthat by the provision of amadhesive' on: the. decorated surface. the material is retained against. removal, such as by windsand'i drafts-of. air;

It is a still. further advantage of: this; invention. that the assembly of. the perforated plates according to this invention. allows for a. tight sealing of the granulated material within. the repository chamber, and 'at thesame time allows easy actuation of the plate with a minimum of wear.
